Question → SQL → DataStory

Question in, answer with its work shown.

Nothing is a black box. Every answer carries the query, the row count, and the runtime.

Ask in plain English

“Which of these vendors is eating the budget?” No SQL, no column names to remember.

The agent writes the SQL

It reads the schema, writes the query, runs it in-browser and hands you the SQL to check.

You get a DataStory™

A short written read on what the numbers mean, with the chart underneath — ready to paste into a thread.
